Pressing esc doesn't completely zoom you out, instead the zoom range is set to ~99% of the interpolated value between currentDomain and maxDomain (almost as if the animation skips the very last frame). Currently, you can press esc repeatedly to converge to the default zoom level.
The same goes for click followed by alt+click.
Can be observed in the interactive demo by looking at the displayed 'Zoom Range' value.
